Olfaction is the sense of smell. The sense of smell is how a man or animal notices a smell (or odour or odor) by using the nose. Many animals have better noses than people. Some animals can detect small particles in the air or sometimes water that people cannot.
People have special cells in the nose that can detect some chemicals. These cells are part of the olfactory epithelium. All vertebrates have these cells. The smell is first processed by the olfactory system. The information is given to the olfactory bulb in the front of the forebrain.
